,, LOCK FOR WINDOW-SASHES.

Patented April 28, 1908.

Application filed June 10, 1907. Serial No. 378,137.

To all whom it may concern:

Be it known that I, JOHN RUMERY, a citi zen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Looks for Window-Sashes, and do declare that the following is a full, clear, and exact description of the invention which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to looks for window sashes, and the invention consists in a compound lock adapted to lock both sashes in respect to each other and to the window frame also, to the end that either sash may be more or less opened, whether above or below, or both can be opened more or less and locked together in open position and also looked in or to the window casing or frame to prevent their separate or joint movement from the open position in which they are deliberately placed, thus making it absolutely safe to have ground floor windows open at night for ventilation, all substantially as shown and described and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional elevation of a window showing the sashes open above and below and locked together and'to the casing. Fig. 2 is an enlarged sectional elevation in perspective of the meeting portions of the sashes and the casing, and showing a lock in the Fig. 3 is an enlarged inside plan view of the lock. Fig. 4 is a cross section on line 44, Fig. 3, and Fig. 5 is a cross section on line 55, Fig. 3.

The nature and purpose of the invention are fully disclosed in the foregoing description and views, and the invention in detail comprises a suitable cast metal shell or casing consisting of opposite side pieces or members A and B respectively, separably con nected and adapted to be fastened as a whole upon the top of lower sash E at one corner thereof, so that the bolts C and D therein may be in position respectively to engage upper sash F and casing and frame G. The said bolts have troughs or grooves in the respective sides of the said casing adapted to hold them at right angles to each other for joint operation by a single lever H. To this end said lever has two extensions or fingers 3 and l 4, respectively, at right angles to each other inside from or beyond its pivot 2, and extension 3 engages a recess centrally in the side of bolt C and extension 4 engages be tween ears or lugs 5 on the inner end of bolt D. Said bolt D is also scarfed or cut away on one side to make room for bolt C and to afford it the requisite movement lengthwise. This construction effects a substantially uni form positive simultaneous movement of both bolts through lever H, and a wire spring J set over pin 6 is interposed between a flange 7 on casing B and lever H outside its pivot to normally hold said lever in looking position for the bolts. T his'enables a person to set the look mechanism in any desired position and leave it there under the action of said spring, but when it is desired to hold the bolts open and confine them in retirement so as to freely move the sashes I turn the pawl L into locking position against lever H. Said pawl or lock is pivoted on pin 8, and has a handle h to control the same. When closed, as in dotted lines Fig. 3, the said pawl stands square against handle H opposite spring J, suspending for the time being the action of said spring. In this position of the bolts the two sashes are free and independent and can be separately moved to any desired position, and the bolts are retracted or withdrawn temporarily when the sashes are being arranged for ventilation or being opened or closed. In this connection it is to be understood that upper sash F has a series of bolt holes on its inner side over which is placed a perforated plate or strap 9, and

similar holes are formed in the runway of lower sash E which are covered by perforated plate or strip 10.

In operation, the sashes are first adjusted according to the opening desired above or below or both and then the bolts are shot to locking position. This both locks the sashes together so that neither can be moved alone, and jointly to the casing so that they cannot be moved together, and the construction and arrangement of the bolts is such that they cannot be tampered with from the outside.

In fact, nothing but the breaking of the glass will enable one to approach the bolts from the outside.

Another advantage of spring J in addition to pressing bolts O and D to locking position is to hold them tight in their respective engagements and prevent rattling when the I a window casing, said casing and upper sash window is shaken by the wind or the like. having a series of holes each for said bolts, That I claim is and a pivoted lock L constructed to engage A window-sash lock having two locking said lever and prevent opening the same.
